Serranus atricauda is a demersal species that is found over rocky substrates from the subtidal zone to depths of 150 m (Cuyas et al. 2004). This is a generalist species, predominantly feeding on crustaceans and smaller fish. Spawning can take place throughout the year (García-Díaz et al 2006). Serranus atricauda is a hermaphrodite and maturation occurs at 4 years old (Costa 1997). The species is highly territorial (Cuyas et al. 2004).

Trophic Strategy
Blacktail comber is a serranid fish that lives on rocky bottoms, from the shallow subtidal down to about 90 m depth. This species is a hermaphrodite, which in the Azores matures at about 250 mm total length and spawns from July to September (Lourinho, 1998). Maturation length corresponds to about 4 years of age (Costa, 1997).

Justification
Serranus atricauda has been assessed as Data Deficient. Although this species is known to be targeted by local semi-subsistence fisheries in areas of its range, the exact extent and impact of this threat is unknown. It is also possible that this species is being impacted by habitat degradation, but it is not known whether this is acting as a major threat at present. Monitoring of the harvest levels, extent of harvest and habitat status of this species is needed before a more accurate assessment of its conservation status can be made.

Population Trend
Serranus atricauda is described as relatively abundant but likely to have declined (Morato et al. 2000). Densities of this species have been recorded as 0.04 individuals per 250m2 in Cabo de Palos Marine Protected Area and 0.3 individuals per 250m2 in Cabo de Gata Marine Protected Area (Charton et al. 2000). Significant decreases in catches have been recorded around the Canary Islands since the second half of the 1980s (Cuyas et al. 2004).

Major Threats
Serranus atricauda is one of the species targeted by the local semi-subsistence fishing industry around the Azores, of which the main catching methods are rod and line from near-shore boat, and coastal nets (Moranto et al. 2000). Its near-coastal habitat is likely to have been degraded by pollution from human settlements, including agricultural run-off and sewage.
While this species is considered to be relatively abundant (Morato et al. 2000), human fishing pressures have impacted the abundance of this species in islands around the Canarian Archipelago. In the same area, two larger serranid species have been severely overfished and stringent management measures for the area have been recommended (Tuya et al. 2006).
This species is commercially harvested throughout its range.

Conservation Actions
Conservation Actions
In 1986, the Canarian Government imposed a minimum length of capture (15 cm total length) for the Archipelago (Cuyas et al. 2004). There are no other known species-specific conservation measures in place for Serranus atricauda. However, its distribution may cover a number of marine protected areas including Selwo Marine Park off southern Spain.
Monitoring of the harvest levels, extent of harvest and habitat status of this species is needed.
